How to fix?

Upgrade SLES:15.0 cross-hppa-binutils to version 2.31-6.3.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream cross-hppa-binutils package and not the cross-hppa-binutils package as distributed by SLES. See How to fix? for SLES:15.0 relevant fixed versions and status.

The swap_std_reloc_in function in aoutx.h in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, allows remote attackers to cause a denial of service (aout_32_swap_std_reloc_out NULL pointer dereference and application crash) via a crafted ELF file, as demonstrated by objcopy.
